The i18n features of CakePHP use po files as their translation source. PO files integrate with commonly used translation tools like Poedit.
The i18n shell provides a quick and easy way to generate po template files. These templates files can then be given to translators so they can translate the strings in your application. Once you have translations done, pot files can be merged with existing translations to help update your translations.
POT files can be generated for an existing application using the
command. This command will scan your entire application for
function calls, and extract the message string. Each unique string in your
application will be combined into a single POT file:
bin/cake i18n extract
The above will run the extraction shell. The result of this command will be the
file src/Locale/default.pot. You use the pot file as a template for creating
po files. If you are manually creating po files from the pot file, be sure to
correctly set the
Plural-Forms header line.
You can generate a POT file for a specific plugin using:
bin/cake i18n extract --plugin <Plugin>
This will generate the required POT files used in the plugins.
Sometimes, you might need to extract strings from more than one directory of
your application. For instance, if you are defining some strings in the
config directory of your application, you probably want to extract strings
from this directory as well as from the
src directory. You can do it by
--paths option. It takes a comma-separated list of absolute paths
bin/cake i18n extract --paths /var/www/app/config,/var/www/app/src
You can pass a comma separated list of folders that you wish to be excluded. Any path containing a path segment with the provided values will be ignored:
bin/cake i18n extract --exclude vendor,tests
--overwrite, the shell script will no longer warn you if a POT
file already exists and will overwrite by default:
bin/cake i18n extract --overwrite
By default, the extract shell script will ask you if you like to extract
the messages used in the CakePHP core libraries. Set
--extract-core to yes
or no to set the default behavior:
bin/cake i18n extract --extract-core yes // or bin/cake i18n extract --extract-core no
